Results vary considerably from person to person. Individuals whose discoloration is primarily caused by coffee, tea, wine, or smoking often notice the greatest improvement because these are surface stains.
However, intrinsic stains caused by aging, medications, or enamel thinning generally require professional dental treatment for significant whitening.
No home remedy can permanently whiten teeth in one minute, but occasional gentle polishing may help restore some natural brightness and improve overall appearance.
